Abstract: A transmission method for transmitting a first modulated signal and a second modulated signal in the same frequency at the same time. Each signal has been modulated according to a different modulation sheme. The transmission method applies precoding on both signals using a fixed precoding matrix, applies different power change to each signal, and regularly changes the phase of at least one of the signals, thereby improving received data signal quality for a reception device.

Abstract: Methods, systems, and devices for wireless communications are described. A base station may transmit an encoded transmission via a broadcast to multiple user equipment (UE). Subsequently, the multiple UEs may transmit assistance information to the base station based on attempting to decode the broadcasted encoded transmission. If the decoding is unsuccessful for at least one UE, the base station may then transmit an additional encoded transmission via a unicast or multicast message to the UEs that were unsuccessful. Additionally, the base station may transmit configuration information for the multiple UEs to receive the encoded transmissions and to transmit the assistance information. For example, the configuration information may include portion information for how long the encoded transmission is transmitted via the broadcast, via the unicast, when to transmit the assistance information, etc. In some cases, the configuration information may be based on UE metrics of the multiple UEs.

Abstract: Disclosed are a codebook processing method, a terminal device, and a network device, the method comprising: determining weighting coefficients for codebook calculation based on a first number and a second number, wherein a value of L representing the first number is half of a number of spatial beams, a value of M representing the second number is a number of discrete fourier transform (DFT) basis vectors. L and M are both integers, and the weighting coefficients comprise amplitude coefficients; performing processing on the weighting coefficients; and transmitting the processed weighting coefficients to a network device through channel state information (CSI).

Abstract: Systems and methods are provided to address issues related to poor radio conditions (e.g., SS-RSRP/SS-RSRQ/SS-SINR) associated with poor coverage for user devices (e.g., user equipment (UEs)) positioned between Synchronization Signal Block (SSB) beams emitted from a cell tower. Specifically, Next Generation Node B (gNB) may identify the location of the user devices (reporting poor signal strength due to poor radio conditions) based on angle or arrival and/or timing advance. Systems and methods further include controlling a phase and amplitude of the SSB beam(s) serving the user device to improve the signal strength of these user devices experiencing poor radio conditions, until the signal strength is within/above target threshold value(s). In this manner, user coverage is improved, with the option to prioritize premium subscribers, without the need for employing a more expensive alternative (e.g., building additional cell sites and towers) for improving user coverage.

Abstract: Systems and methods for wireless communications comprising a plurality of agents, which together as the group, are configured to: (i) wirelessly broadcast an interference signal by forming a radiation pattern having null vectored substantially toward a client; (ii) wirelessly transmit a communication signal to the client by forming a radiation beam carrying the communication signal vectored substantially toward the client; and (iii) wirelessly broadcast a combined communication signal and interference signal to the client using phases of processes (i) and (ii). In some embodiments, the agents together as a group may be further configured to: allocate and adjust power for performing processes (i) and (ii) at substantially the same time.

Abstract: A communication system includes multiple distributed antenna circuits and an access point (AP). The distributed antenna circuits include at least first and second antenna circuits. The AP is coupled to the distributed antenna circuits and includes multiple transmit chains, multiple receive chains, and an antenna control circuit communicatively coupled to the transmit chains and the receive chains. The first antenna circuit is co-located with the AP and the second antenna circuit is remote from the AP. The antenna control circuit is configured to determine a subset of the distributed antenna circuits to communicatively couple to at least some of the transmit chains to transmit data to a wireless station (STA) that is in range of the subset.

Abstract: A communications network system is disclosed. The system may include a central processing unit (CPU) in data communication with a first access point (AP) configured to enable a data communication between the CPU and a first user equipment (UE). The CPU may include a processor configured to select a first group of APs including the first AP, establish a first data communications link over a first frequency band between the CPU and the first AP, cause the first AP to establish a second data communications link over a second frequency band between the first AP and the first UE, and transmit a portion of data to the first AP over the first data communications link. The first data communications link may be a wireless data communications link. The first frequency band may include higher frequency levels than those of the second frequency band.
